From 4d52a25326506f8a3e876ded029ff4db7749f8a9 Mon Sep 17 00:00:00 2001 From: Török Edwin Date: Thu, 6 May 2010 22:19:57 +0100 Subject: gallivm: Require SSE2 for draw_llvm/llvmpipe due to LLVM PR6960. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Note that this also requires X86 for llvm, if llvmpipe/draw_llvm works on PPC then the condition should be extended to include && x86.
